"The animal seems to be too big for arboreal life, and its hind limbs were built rather for great speed on the ground, purely as a protective function. It seems possible that the fore limbs bore a narrow patagium, which might be of use in rapid flight along the ground as indicated in the accompanying restoration (Fig. 16). By throwing the head and forearms well forward the thrust of the femora would be turned more forward than upward, while at the same time the forearms if phovided with patagia would serve to keep the fore part of the body from pitching downward." (Notes on the Habits of Struthiomimus by Dr. Williamn K. Gregory / Osborn, 1917)

"It presents a punctured surface, but there is no indication of a regular pattern and no evidence of dermal ossifications, though Nopcsa has reported the presence of thin ossifications with the remains of Hypsilophodon that are regarded by him as pertaining to the skin." (Gilmore, 1915 / Preservation of the epidermis, pag. 611)

"Gilmore states that in preparing his restoration model an attempt was made to express the light, agile nature of Thescelosaurus (4, p. 615). The fairly heavy ribs and limbs, the short, broad scapula, and the broad back do not suggest to me that Thescelosaurus was as slender as shown by Gilmore in his model. (...) Skin impression over the limbs of the type of Lambeosaurus clavinitialis suggests that in the hadrosaurs at least the femur was enclosed in the flank. It does not seem likely that the hind limbs of Thescelosaurus would be cut away as much from the body as shown by Gilmore." (Sternberg, 1940)

"Jay H. Matternes and Norman N. Deaton began the preparation of four dioramas for exhibition on the balcony of the hall. With animal figures at a scale of one inch to a foot, these will depict land vertebrates of the Upper Triassic, Upper Jurassic, and Upper Cretaceous, and sea vertebrates of the Upper Cretaceous.

Artist Jay H. Matternes completed for the age of mannnals hall a third mural painting. It depicts terrestrial life during the Oligocene in North America. Specifications were prepared for the fourth mural, which will represent an animal assemblage of the Pliocene epoch." (1963 / fonte: Annual report for the year ended June 30)
